### 21.1 Understanding how Eclipse Help works

Eclipse Help for the Eclipse Platform is based on an XML table of contents that specifies the structure of the Help system and references content in standard XHTML files. An Eclipse Help plug-in minimally consists of a plug-in manifest file, plugin.xml, and a TOC (table of contents) file, toc.xml. The manifest provides information about the plug-in, such as name, ID, and version number. The TOC file is registered with the Eclipse Platform, using the org.eclipse.help.toc extension point.

DITA2Go supports the core functionality of Eclipse Help, including the following:

- generation of primary and secondary TOCs
- indexing (for later versions of Eclipse)
- infopops: the Eclipse version of CSH (Context-Sensitive Help).
